If the Planck length got bigger, you would start to observe quantum behavior for larger particles than you were accustomed to seeing. From a pilot wave perspective, the scale of a wave relative to the Planck length determines whether or not you will observe classical or quantum behavior.
What if Planck’s constant was larger?
What would happen if Planck’s constant was smaller?
The Planck constant sets the scale for where quantum mechanics becomes significant. If it were smaller, a system would have to be smaller to behave in a quantum-like manner. For some purposes (e.g., complementary variables ), zero would correspond to classical mechanics.
Why is Planck’s constant so small?
So why is the Planck length thought to be the smallest possible length? The simple summary of Mead's answer is that it is impossible, using the known laws of quantum mechanics and the known behavior of gravity, to determine a position to a precision smaller than the Planck length.
What does Planck’s constant tell us?
Planck's constant defines the amount of energy that a photon can carry, according to the frequency of the wave in which it travels.
Can anything be smaller than the Planck length?
Originally Answered: Is there anything smaller than a Planck length? There is no even theoretically possible measuring device that can measure differences between two locations that are closer together than a Planck length. Thus, the Planck length is the smallest possible unit of measurement.
Is Planck’s constant infinite?
I think the most precise numbers measured in physics have been found that way. But to increase the accuracy of measurement so the interval of possible values gets smaller doesn't make the number of possible true values less. It's still infinite.
Is Quantum Foam real?
There is no such thing as empty space; there is only 'quantum foam,' everywhere. Such is space-time for a quantum physicist. … “Because these bubbles are so small and last for such a short time, they can never be observed directly,” says Perlman. “But they would affect light in an interesting way.”
What is the smallest possible time?
What is a zeptosecond? A zeptosecond is a trillionth of a billionth of a second. That's a decimal point followed by 20 zeroes and a 1, and it looks like this: 0.000 000 000 000 000 000 001. The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time.
How was Planck’s constant determined?
Through the direct use of Einstein's photoelectric equation, the Planck constant is determined by accurately measuring the energy position of the gold Fermi level using light sources with various photon wavelengths.
